Water shut-off location:

In the event of a water emergency, the master water shut-off valve is usually located next to or near your water meter. The water meter is usually located at the point where the water pipe comes through the foundation, usually in the basement or utility room.

Sewer Back Ups:

In the event that you experience a sewer backup, we request that you first call us to determine if the main sewer line is blocked and is the cause of the problem. We will promptly respond to your call, and if the problem is in the sewer main, you will save the time and expense of having a plumber work on the property owner's sewer lines or laterals.
